Controller Properties dialog box - Network tab settings

Use the settings on the
Network
 tab of the
Controller Properties
 dialog box to configure settings and monitor faults for a Device Level Ring (DLR) topology. The settings are available when online.
The ability to change the settings on this tab can be controlled by
FactoryTalk Security
 permissions.
Parameters
Description
Network Topology
Displays the current network topology as either:
  • Linear/Star
  • Ring
Network Status
Displays the current network status as:
  • Normal
  • Ring Fault
    , or
  • Unexpected Loop Detected
Active Ring Supervisor
Displays the IP Address or MAC Address of the active ring supervisor.
The ring supervisor provides the following primary functions:
  • Verifies the integrity of the ring.
  • Re-configures the ring to recover from a single fault.
  • Collects diagnostic information for the ring.
Active Supervisor Precedence
Displays the precedence assigned to the active supervisor when the network is operating in a Ring mode.
Enable Supervisor Mode
Indicates whether the controller's Supervisor Mode is enabled or disabled. Select the check box to configure the controller as a supervisor on the network.
Ring Faults Detected
Displays the number of ring faults detected on the network since the last power cycle or counter reset. Only available when the controller is a ring supervisor.
Reset Counter
Resets the controller’s ring fault count to zero. This command is only available when the controller is a ring supervisor.
Supervisor Status
Displays the controller’s ring supervisor status. This command is only available when the controller is a ring supervisor.
  • Active
     - The controller is the Active Ring Supervisor.
  • Backup
     - The controller is a backup supervisor.
  • Cannot support current Beacon Interval or Timeout
     - The controller cannot support either the beacon interval or timeout values of the current Active Ring Supervisor.
Last Active Node(s)
Displays the IP Address or MAC Address of the last active nodes on Port 1 and Port 2 if a ring fault has occurred.
This command is only available when the controller is a ring supervisor.
Verify Fault Location
Causes the active ring supervisor to verify the last node fault location on port 1 and port 2 of the controller.
The last fault location that has occurred continues to display until you verify the fault.
This command is only available when the controller is a ring supervisor.
Status
Displays whether a fault exists on the ring. Available values:
  • Partial Network Fault
     - Occurs when traffic is lost in only one direction on the network because a ring member is not forwarding beacons in both directions.
  • Rapid Fault/Restore Cycles
     - Any of the following may cause a rapid ring fault:
    • Five intentional disconnections/re-connections of a node from the network within 30 seconds
    • A duplex mismatch between two connected devices
    • Electromagnetic noise on the network
    • Unstable physical connections, such as intermittent connectors
Given the nature of a rapid ring fault, the
Last Active Node
 information may not be accurate when a rapid ring fault condition is present.
Clear Fault
Clears the rapid fault/restore cycles fault. This command is only available when the controller is a ring supervisor and there is a rapid ring fault.
Advanced
Opens the
Advanced Network Configuration
 dialog box to configure advanced network properties.
